Very nice product..! It was really hard to find a Dealer for it
on the web. Can you share a source/dealer where you bought/buy
yours?

Very, very nice... the current generation of solar electronics
is finally coming into "their prime" / great features per
dollar spent.

Nice, I believe many of the current generation repeaters
on the market have similar features. For the older stuff,
we have to do it by retrofit.
One could copy the power fail circuit from the Motorola
Spectra Tac remote receiver. The power fail alert-tone
feature is great but you always seem to end up having to
explain it the user(s) each time it triggers.
